IMPROVEMENT IN BOTTLE-STOPPERS.

Specification forming part of Letters Patent No. 153,746, dated August4, 1874; application filed July 11, 1874.

To all whom at may concern:

Be it known that I, EDWARD CLARK, of Newark, in the county of Essex andState of New Jersey, have invented a new and Improved Bottle-Stopper, ofwhich the following is a specification:

This invention consists of a stopper for still liquors, made of aspherical or approximately spherical ball, of cast metal, having a wirespring passing transversely through the upper portion, and apacking-disk, of elastic material, with a hole in the middle, stretchedover the lower portion, into an annular groove a little above thebottom, which is pressed down airtight into the nozzle by the springbeing jointed at one end to a wire fastened to the neck of the bottle,and at the other end sprung under a hook ofsaid Wire, the wire havingtwisted projections on opposite sides of the neck, extending upwardsuitably for so connecting the spring. The ball is made of soft metal,or composition of metals, and is cast on the spring.

The contrivance makes a very cheap stopper, for one having permanentconnection to the bottle, for continual use.

Figure 1 is a sectional elevation of the stopper, and a bottle to whichit is attached. Fig.

2 is a side elevation of the ball; and Fig. 3 is a plan of the elasticwasher.

Similar letters of reference indicate corresponding parts.

A represents the metal ball; B, the wire spring; 0, the elastic washer,and D the wire fastened around the neck of the bottle for holding thespring, which is jointed or hinged to it at E and hooks to it at F, saidwire being so adjusted that the spring has to be pressed down smartly tohook onto it. The hook may be formed either on the spring B or wire D. bis the groove in the ball for receiving the elastic washer, which isapplied by stretching the hole 01 over the head 0. It is curved in theupper wall, as'shown at a, to

conform to the shape which the washer assumes when pressed down into thenozzle.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent- The ball A, elastic washer O, springB, andfastening-wire D, combined with a bottle, in the manner described, toform a stopper.

EDWARD CLARK.
